REPUBLIKA.CO.ID, JAKARTA -- The death toll in a magnitude-7 earthquake which rocked Lombok and Sumbawa Islands in West Nusa Tenggara (NTB) province on Sunday night rose to 91 as of Monday. The figure was predicted to increase as search process continues.

Of the 91 dead victims, 72 were found in the Districts of North Lombok, 9 bodies in West Lombok, two bodies in Central Lombok, two bodies in East Lombok, and four bodies in the provincial city of Mataram. Two other victims died in Bali, the neighboring province.

"Most of the victims died from collapsed buildings," Sutopo Purwo Nugroho of National Disaster Mitigation Board (BNPB)'s data center and public relations said in a press conference on Monday morning.

The quake which rattled the two islands at 6:46 p.m. local time on Sunday was centered 8.3 degrees southern latitude and 116.48 degrees eastern longitude, and at a depth of 15 kilometers.

The Meteorology, Climatology and Geophysics (BMKG) issued a tsunami early warning shortly after the quake and lifted it at 9:25 p.m. local time on Sunday.

TNI personnels carry the dead victim's body to an ambulance at parking lot of North Lombok District General Hospital in Tanjung, North Lombok, West Nusa Tenggara, on Monday.

Meanwhile, BMKG recorded 132 aftershocks as of morning on Monday after the earthquake rocked Lombok in West Nusa Tenggara province on Sunday night. The aftershocks had steadily declining intensity, the BMKG said in a statement received early Monday.

However, the magnitude was quite big 5.4 at around 07.28 WIB. As the local residents still felt the aftershocks, they opted to save themselves in open space, the agency said.

An earthquake measuring 7.0 on the Richter scale shook the islands of Lombok and Sumbawa in the province on Sunday night. BMKG said the magnitude-7 quake was the main shock of the series of quakes which hit the province earlier.

The magnitude 7 quake almost had the same epicenter as the magnitude 6.4 quake which hit the province on July 29 this year.

Judging by its epicenter, hypcenter depth and source mechanism, the quake is a shallow quake due to the activity of Flores back arc trust.
